Steel wire armoured cable, commonly abbreviated as SWA, is a hard-wearing power cable designed for the supply of mains electricity. It is one of a number of armoured electrical cables – which include 11kV Cable and 33kV Cable – and is found in underground systems, power networks and cable ducting.

Distribution cable is the most popular indoor cable, as it is small in size and light in weight. They contain several tight-buffered fibers bundled under the same jacket with Kevlar strength members and sometimes fiberglass rod reinforcement to stiffen the cable and prevent kinking. These cables are small in size, and used for short, dry conduit runs, riser and plenum applications. The fibers are double buffered and can be directly terminated, but because their fibers are not individually reinforced, these cables need to be broken out with a “breakout box” or terminated inside a patch panel or junction box to protect individual fibers.

Another “cable” type is not really cable at all. By installing a “cable” which is just a bundle of empty plastic tubes, you can “blow” fibers into the tubes using compressed gas as needed. If you need to upgrade, blow out the old fibers and blow in new ones. Both indoor and outdoor versions of air-blown fiber cables are available and its even been used for FTTH. Special fibers are required that have been coated for easier blowing through the tubes, but any singlemode or multimode fiber is available. It’s more expensive to install since the tubes must be installed, special equipment and trained installers are needed but can be cost effective for upgrades.
